Recent Evidence
In a study with more than 1200 5th graders using a process of scaffolded guided inquiry with embedded writing strategies experimental group students significantly outperformed the control group who received regular instruction using just kits and just testbooks on posttest, state science standards scores and writing scores.
EL closed achievement gap with EO students in experimental group
At a middle school with 288 8th graders (99.7% Free and Reduced Lunch, 77.8% EL), a similar method was used. 63% of the students scored Proficient or Advanced on the 2006 administration of the California Science Standards Test.

How Students Learn ScienceNational Research Council (2005)
� Engage to activate prior knowledge
� Develop competence
� Deep foundation of factual knowledge
� Understand facts in the context of big ideas
� Organize knowledge to facilitate retrieval
and application
� Utilize metacognitive approaches to instruction

Key Issues:Teachers of Science are Teachers of Language
� Are the special challenges of scientific oral and written discourse and vocabulary, included in instructional design?
� Is the rigor of academic language increased incrementally as students progress to higher levels of English Language Development?
� What are the efficient and supportive ways to provide feedback to students on their written and oral work within the context of science instruction?

Kit Inventory
� Prediction� Student/Teacher pull out one item at a time. Students predict what they think it might be used for.
� Classifying� Teacher distributes items. Students match items they feel are used together or fall under the same category. Students may identify properties of items.

Kit Inventory
� Prior Knowledge
� Students discuss which items they’ve previously used and how
� Description
� Students take an item from kit and describe it by using their senses. They can play a guessing game with class/partner.

National Research Council (2001)
“Investigations can be highly structured by the teacher so that students proceed toward known outcomes, such as discovering regularities in the movement of pendulums. Or investigations can be free-ranging explorations of unexplained phenomena… The form that inquiry takes depends largely on the educational goals for students, and because these goals are diverse, highly structured and more open ended inquires both have their place in science classrooms” (NRC, 2001, p. 10-11).

More Research to Consider
� Students benefit from strong scaffolding with respect to building explanations from evidence (Songer and Lee, 2003)
� Questioning, predicting, clarifying, and summarizing are strengthened through scaffolding. Clarifying promotes comprehension monitoring. Students benefit from scaffolding when analyzing data and building explanations from evidence. (Hug, Krajcik and Marx, 2005)
� A process of scaffolded inquiry, reflection and generalization developed students’ metacognitiveknowledge. (White and Fredrickson, 1998)
![Page 43: Effective Classroom Practices--English Learner Development Strategies in Science · 2011. 7. 21. · Slide 1 Effective Classroom Practices –English Learner Development Strategies](https://reader030.vdocuments.us/reader030/viewer/2022012001/60802c4369dcae4d8359b00c/html5/thumbnails/43.jpg)

� Writing may force the integration of new ideas and relationships with prior knowledge and encourage personal involvement with the new information (Kleinsasser, et al, 1992)
� Written and oral language opportunities to explain, describe, predict and integrate new information allow students to make conceptual shifts and facilitate retention (Fellows, 1994)

Effect of Talk and Writing on Learning Science
� Talk is important for sharing, clarifying, and distributing knowledge among peers.
� Asking questions, hypothesizing, explaining, and formulating ideas together are all important mechanisms during peer discussions.
� Writing is an important tool for transforming claims and evidence into knowledge that is more coherent and structured.
� Talk combined with writing appears to enhance the retention of science learning over time.
(Rivard and Straw, 2000)

Conclusions
� All of these findings were found in a set of school districts and schools who have very high ELL populations (70-85%)
� Students receiving scaffolded guided inquiry instruction in both grade 4 and 5 produced student notebooks that were significantly different than control group with respect to:
� Quality of Communication
� Science Conceptual Understanding
� Use of scientific vocabulary

Next Steps
� Same studies were replicated in the same schools with the same teachers for 2005-2006 and 2006-2007
� Grade 4 students from 2004-2005 were tracked longitudinally to create a 2X2 design in grade 5 for 2005-2006 and repeated in 2006-2007.
� Entire study is being replicated in Wake County Public School System (North Carolina) in 2006 -2007.
